I'm dropping this from the game in favour of a more dynamic system, but I wanted to keep this around somewhere because 
I'll be using this 'pattern' for something similar again and didn't want to fuss with sytax.  Maybe you'll find it useful

/*
I completely ripped this off of Orson Peters' ed25519 implementation to make it a single file.  I added mg_ed25519 prefixes
to everything so it wouldn't pollute the global namespace, but otherwise the code is the same.
The original implementation is here: https://github.com/orlp/ed25519
